| How you get sponsors | You filter sponsors by niche and newsletter size, copy a drafted pitch and send it from your own inbox | It emails the brands that sponsored newsletters like yours and introduces you when one replies |

Which one costs less?
SponsorDB prints one plan: $20 a month. Book a Sponsor prints its plans: Starter $19 a month for up to 600 emails a month, Kit $49 a month for up to 1,500 emails a month, Growth $99 a month for up to 3,000 emails a month. The bigger difference is who sends the emails.
Newsletters under 5,000 subscribers list one main slot at a median $150 (79 newsletters), and those with 5,000 to 19,999 at $300 (114 newsletters, read 4 November 2026 by Book a Sponsor). One such sponsor covers 7 or 15 months of SponsorDB. SponsorDB pricing has what the plan includes.
Is a list of 440 sponsors enough?
It depends on your niche. SponsorDB's homepage says 440+ verified sponsors found in 110+ newsletters, and its FAQ says 100+. We did not subscribe, so we could not see the full list. Book a Sponsor has seen 8,550 brands sponsoring 4,988 newsletters.
A short list can still be the right one if it only holds brands already buying in newsletters your size. SponsorDB filters on that, which is the same idea as Book a Sponsor's match on the newsletters most like yours.
